Opencart 搜索页面自定义产品 link 结构

Opencart search page custom product link structure

默认情况下,在Opencart中,当我搜索产品时,在搜索页面上,产品以以下link结构出现:sitename/product-name/?search=,但我想将其更改为sitename/category/subcategory/product-name

$this->data['products'][] = array(
                'product_id'  => $result['product_id'],
                'thumb'       => $image,
                'name'        => $result['name'],
                'description' => utf8_substr(strip_tags(html_entity_decode($result['description'], ENT_QUOTES, 'UTF-8')), 0, 100) . '..',
                'price'       => $price,
                'special'     => $special,
                'tax'         => $tax,
                'rating'      => $result['rating'],
                'reviews'     => sprintf($this->language->get('text_reviews'), (int)$result['reviews']),
                'href'        => $this->url->link('product/product', 'product_id=' . $result['product_id'])
            );

'href' 是包含 link 结构的行。

'href'        => $this->url->link('product/product', 'product_id=' . $result['product_id'])
            );

我前阵子为此写了一个函数,你可以随意使用它。唯一的问题出现在产品属于多个类别时,在这种情况下,函数会选择最深层次的类别来生成完整路径。如果同一深度级别存在多个匹配项,它将选择第一个匹配项。

将此函数添加到/catalog/model/catalog/product.php的末尾:

public function getProductCategoryPath ($product_id) {
    $query = $this->db->query("
        SELECT GROUP_CONCAT(path_id ORDER BY LEVEL ASC SEPARATOR '_') as path 
        FROM " . DB_PREFIX . "product_to_category
            LEFT JOIN " . DB_PREFIX . "category_path USING (category_id)
        WHERE product_id = '" . (int)$product_id . "'
            AND category_id =
            (
                SELECT category_id 
                FROM " . DB_PREFIX . "product_to_category c 
                LEFT JOIN " . DB_PREFIX . "category_path cp USING (category_id) 
                WHERE product_id = '" . (int)$product_id . "' 
                AND cp.level =
                (
                    SELECT max(LEVEL) 
                    FROM " . DB_PREFIX . "product_to_category
                    LEFT JOIN " . DB_PREFIX . "category_path USING (category_id)
                    WHERE product_id = '" . (int)$product_id . "'
                )
                ORDER BY category_id LIMIT 1
            )
        GROUP BY category_id
    ");
    return $query->num_rows ? $query->row['path'] : false;  
}

然后在您发布的块之前修改 catalog/controller/product/search.php 以调用函数,如下所示:

$path = $this->model_catalog_product->getProductCategoryPath($result['product_id']);
$url = $path ? '&path=' . $path : '';

$this->data['products'][] = array(

解释:

函数中的查询首先查找链接到产品的所有类别。接下来,它找到最深的级别并选择它遇到的第一个类别,该类别既匹配该级别又被分配给产品。然后它使用 GROUP_CONCAT 根据所选类别构建类别层次结构的路径字符串。

然后在 search.php 控制器中调用此函数,如果结果非空,我们将搜索 url OpenCart 替换为函数返回的类别路径字符串。

你可以的。这是 link 到产品 echo

的 href link
$product['href'] <h4><a href="<?php echo $product['href']; ?>"><?php echo $product['name']; ?></a></h4>
